Fratty as Fuck. A phrase describing a bro on all standards. The guy at a party that runs shit. He has the biggest entourage, can outdrink everyone, is wasted as shit, and still gets the finest pieces in the joint, often times two at a time. In summary someone who wherever they role, don't give a fuck because shit either goes their way or they make it so.

Yo how is he leaving with them three sorostitue dime pieces when he was just telling them to fuck themselves?

This acronym for the term was coined in Essex, England, and since then has been frequenly used by the whole teenage age group, especially those in the Alternative music scene. It can quite commonly be found on Myspace, a popular internet socialising website.

Please note: F.A.F. has a dot after the second F to add emphasis. The conventional F.A.F is more widely used. The extra dot may also added to avoid the certain 'chaviness' surrounding the more common form.
